Abstract
A water craft or land vehicle is stabilized against rolling and pitching forces by a mass or masses rotating about a vertical axis. The mass or masses are distributed along the vertical axis so that the center of the overall mass lies on the roll and pitch axes so that resistance to roll and pitch is exerted without precession. The gyro is gimballed along two axes which coincide with the roll and pitch axes. A stop mechanism allows a free pitching and rolling through a small angle before gyro resistance is met. Hydrofoils may be extended and retracted under pitch and roll signals from the gyro for extra stability.
Claims4
In a vehicle having a propensity to roll about a horizontal, longitudinal roll axis extending along the direction of travel and to pitch about a horizontal pitch axis transverse to the roll axis, a stabilizing apparatus comprising:
- a gyro frame assembly mounted on the vehicle for rotation about a horizontal longitudinal, roll first axis and for rotation about a horizontal transverse pitch second axis;
- independently adjustable first stop means operatively connected to the gyro frame assembly for preset limiting of the amount of rotation about the first axis independent of rotation about the second axis;
- independently adjustable second stop means operatively connected to the gyro frame assembly for preset limiting of the amount of rotation about the second axis independent of rotation about the first axis;
- a gyro rotor assembly rotatably mounted on the gyro frame assembly for rotation about a vertical rotor axis;
- the gyro rotor assembly having a rotary mass distributed along the rotor axis such that the center of the rotary mass lies substantially on the first and second axes;
- means for driving the rotary mass at gyroscopic rotational velocities;
- and
- wherein the gyro rotor assembly resists torque on the vehicle about the roll axis and the pitch axis that exceeds the amount of rotation about the first and second axes preset by the stop means without substantial precession.
